## Hesher 3 years ago Find the Slope of the line through points: (-3,-4) and (16, 8)

1. yazthespaz

There is a special formula for this, do you know what it is?

2. Hesher

Wouldn't the steps be to do: Y2 - Y1 Over X2 - X1

3. yazthespaz

Yes great!

4. Hesher

That part I do know, but it's the part that comes after I'm not so sure of

5. yazthespaz

So now you can just pick which ever points you wan as Y2 X2 and so on

6. Hesher

Is the answer always supposed to be a fraction?

7. yazthespaz

technically not

8. yazthespaz

for example if you get 10/5 the slope might end up being 5 which would technically be 5/1 in rise over run form. Making 5 rise and 1 run

9. yazthespaz

I'm sorry the slope will end up being 2*

10. Hesher

oh, I forgot I was supposed to simplify

11. yazthespaz

always, but when you graph the fraction even if you get slope 4 for example you would still move 1 to the right. Did i answer your questions?

12. Hesher

Yes you did. Thank you!

13. yazthespaz

No problem!

14. Hesher

Just one last thought, but it is common for the rise to be negative sometimes right?

15. yazthespaz

yes, but when your simplifying the slope form, if the rise is negative the whole slope is negative just like when the run is negative the whole slope is negative

16. Hesher

I see

17. yazthespaz

basically the rise cannot be negative and the run is positive, if one is negative they are both negative

18. yazthespaz

or vise versa

19. Hesher

Ahh, I see it now. Thank you

20. yazthespaz

No problem
